In its support forums, Bose has indicated that it plans to add AirPlay 2 support to select SoundTouch speakers and other systems by the end of February.
The following products will be included:
SoundTouch 10
SoundTouch 20 series III
SoundTouch 30 series III
SoundTouch SA-5 amplifier
Wave SoundTouch music system IV

AirPlay 2 support will likely be rolled out as part of a free over-the-air software update via the Bose Music app for iPhone and iPad.
AirPlay 2 enables multi-room audio playback with other AirPlay 2 devices, such as the HomePod, Apple TV, and select speakers from Sonos, Bose, Bowers & Wilkins, and others. AirPlay 2 devices also appear in the Home app on the iPhone, iPad, Mac, and Apple Watch and can be controlled with Siri voice commands.
Bose added AirPlay 2 to select BoseSmart speakers and sound bars last year.
